User-Agent Switcher

This Opera extension adds a toolbar button and a menu to switch between user-agents.

Browse with our predefined user-agents or add your own user-agents.

Changing User-Agent allows you to mimic, spoof or fake other browsers, devices or search engine spiders.

The extension does not render web pages in the same way as the selected one. User-Agent Changer is primarily for developers who want to test how a page responds to different browsers. Switching User-Agent may also be used to reach certain pages that allows a particular browser.

You can change User-Agent back to default when you are done.

This extension also switches the javascript based User-Agent (navigator.userAgent)
